When the suitors retire for the night, Telemachus and Odysseus remove the arms as planned. Athena lights the room for them so that they can see as they work. Telemachus tells Eurycleia that they are storing the arms to keep them from being damaged.
After they have safely disposed of the arms, Telemachus retires and Odysseus is joined by Penelope. She has come from the women’s quarters to question her curious visitor. She knows that he has claimed to have met Odysseus, and she tests his honesty by asking him to describe her husband. Odysseus describes the Greek hero—himself, capturing each detail so perfectly that it reduces Penelope to tears. He then tells the story of how he met Odysseus and eventually came to Ithaca. In many respects, this story parallels those that he told to Athena and Eumaeus in Books 13 and 14, respectively, though it is identical to neither. He tells Penelope that, essentially, Odysseus had a long ordeal but is alive and freely traveling the seas, and predicts that Odysseus will be back within the month.
Penelope offers the beggar a bed to sleep in, but he is used to the floor, he says, and declines. Only reluctantly does he allow Eurycleia to wash his feet. As she is putting them in a basin of water, she notices a scar on one of his feet. She immediately recognizes it as the scar that Odysseus received when he went boar hunting with his grandfather Autolycus. She throws her arms around Odysseus, but he silences her while Athena keeps Penelope distracted so that Odysseus’s secret will not be carried any further. The faithful Eurycleia recovers herself and promises to keep his secret.
Before she retires, Penelope describes to Odysseus a dream that she has had in which an eagle swoops down upon her twenty pet geese and kills them all; it then perches on her roof and, in a human voice, says that he is her husband who has just put her lovers to death. Penelope declares that she has no idea what this dream means. Rising to the challenge, Odysseus explains it to her. But Penelope decides that she is going to choose a new husband nevertheless: she will marry the first man who can shoot an arrow through the holes of twelve axes set in a line.
Penelope and Odysseus both have trouble sleeping that night. Odysseus worries that he and Telemachus will never be able to conquer so many suitors, but Athena reassures him that through the gods all things are possible. Tormented by the loss of her husband and her commitment to remarry, Penelope wakes and prays for Artemis to kill her. Her distress wakes Odysseus, who asks Zeus for a good omen. Zeus responds with a clap of thunder, and, at once, a maid in an adjacent room is heard cursing the suitors.
As the palace springs to life the next day, Odysseus and Telemachus meet, in succession, the swineherd Eumaeus, the foul Melanthius, and Philoetius, a kindly and loyal herdsman who says that he has not yet given up hope of Odysseus’s return. The suitors enter, once again plotting Telemachus’s murder. Amphinomus convinces them to call it off, however, when a portent of doom appears in the form of an eagle carrying a dove in its talons. But Athena keeps the suitors antagonistic all through dinner to prevent Odysseus’s anger from losing its edge. Ctesippus, a wealthy and arrogant suitor, throws a cow’s hoof at Odysseus, in response to which Telemachus threatens to run him through with his sword. The suitors laugh and laugh, failing to notice that they and the walls of the room are covered in blood and that their faces have assumed a foreign, ghostly look—all of which Theoclymenus interprets as portents of inescapable doom.
